OOP code not compatible with PHP4

This module is now basically unusable in PHP4 - it generates a ton of fatal errors (unexpected T_STRING in spaces.module line 231, for example). Given the number of hosts still running PHP4 (including our servers for at least the next month and a half, this is a major problem. I'd urge you to at least keep a PHP4 compatible version available for those of us unable to use PHP5.
